[Python] Treat '.' as the character '.' in fullmatch [duplicate]

Reading 2 files and comparing them line by line. The files contain the character '.' and hence it matches more than '.'. As you know this matches any char. how do I tell fullmatch to treat every char as they are? Should I be using any other function instead of re.fullmatch?

for line1 in lines1:
names1=line1.split(' ')
name1,cname1=names1
for line2 in lines2:
names2=line2.split(' ')
name2,cname2=names2
if re.fullmatch(r"name1", "name2", re.IGNORECASE):
if(cname1==cname2):
next
else:
print(line1," ",line2)
else:
next


sample input

file1:
host1.qa host1.c1.com
file2:
host1-qa host2.d1.com


This script takes host1.qa and host1-qa to be the same due to matching of '.' Need exact match. How to achieve that?
